Building an INFINITE LEGO Train Machine..

This is a lego train, and I'm gonna build it into an endless loop to make it infinite. Or at least, I'm gonna try. Yeah, it is not meant to do that. This is gonna be a massive build, so to get the strength required, I'll use a bunch of these big Technic frames. And no, before you say anything in the comments, putting the lego train on a single loop of track definitely doesn't achieve the exact same thing. I basically need a giant lego train treadmill. So on each end of the beam, I'll use these gears, which will guide a very long section of track into place. That, once motorized, becomes a functional lego worm. Good to see we're on the right track. But don't get too comfortable, because I did not stay on the right track this whole build. In fact, it's seriously gotta be one of the most complicated, frustrating, and rage-baiting builds I've ever made. And you guys will be the judge of my success or failure at the end. But let's not get ahead of ourselves, because we obviously can't have a treadmill rolling around. So using more Technic frames, this time A-shaped ones, I'll lift it off the ground to make a super strong structure. Tracks will come next, and I'll connect them, leaving slight gaps that the train can cross. Except for this one, I don't think it's very smart to have the train jump a six stud long gap. So I use some more pieces as spacers to make the tracks line up just right. Unfortunately, there's a second problem. Because the tracks connection isn't very good, causing them to fall off when they go around the corners of the tread. So I use more plates to increase the surface area connected to the tracks. And to stop the tracks from tipping from the weight of the train on each end, I use little support blocks. Which means now, hopefully, the train can roll just fine along this, just like it would on a normal track. But if there's one thing I've learned from making lego mechanisms, if there's something to catch on, the moving parts will always catch on it. And since there's a decent amount of sag on the bottom part of the tread, it catches on the support beams. But my job fixing that is fairly simple, since I'm working with train tracks, and I can just use a single wheel assembly on each support section to keep the track guided and not catching. It did still catch at first, but I just added another layer of wheels, and then added a little ramp at the front to make sure the track is guided to the right place. And with that done, it actually works super well. That means I now need to motorize it, and I want to make sure this isn't underpowered, so I'm going to add a motor on each side, which is where things got bad. I had switched the lego motors for these extra fast and powerful BuWizz motors, and it turns out when you run a lego worm gear box at super high speeds, bad things happen. All this black buildup is from the axle, and the reason that's there is because the worm gear decided to become a drill and bore right through the side of the housing, cutting a clean hole right through the plastic, and friction welding itself in place with the melted axle. I did not realize there was forces that strong at play here. I tried running the motor in reverse to unstick it, but that and even yanking on the axle didn't move it at all. Well, that's obviously not going to work, so I pivoted back to using the lego motors and building a gear chain that increases torque and reduces speed, which I connected to the tread using this big frame to make sure everything has enough support. Now that that's in place, I'm going to test it out with a train, which I'll hold in place with a chain and a beam across the track. Okay, now it's time for some viewer participation. When I turn the motor on, did the train A, run perfectly smoothly with no problems, B, run for a decent length of time before derailing, C, explode, or D, derail every single time I tried to run it? Wow, how'd you figure out that one? Because of the way lego train tracks connect, they would end up slightly offset, and the little gap would lead the train's front wheels to derail basically every time. But surprisingly, the problem wasn't too hard to fix, since connecting the chain to the beam on the other side seemed to put enough sideways pull on the train to keep it on the right side of the tracks. And finally, it seemed like we're actually getting somewhere. The train treadmill works, and the train stays on, which basically achieves our original goal. But it seems awfully boring, and my whole plan all along was to go much further than this. Picture this meme. But this guy is me, and instead of turning around and leaving with what I've built already, I'm still mining towards the diamonds. But instead of diamonds, there's frustrating lego builds that won't do what I want them to. In other words, I'm now gonna try and build a rotating background display that moves at the same speed as the track, to really sell the idea of the train moving forever. Here's how it'll go. First, I'm building off the back of the existing frame with more frame pieces, and then building up with even more frames, topping it off with another long yellow assembly that will hold another tread. Obviously, we're gonna need it motorized, and since I want it the same speed as the tracks, I made sure to use the same gear ratio setup on these motors as I did down below. And then I connected it up to the tread using universal joints. That worked perfectly, but you'll notice this tread hanging down in the middle, which is gonna be a massive problem down the road. It's also gonna be a massive problem if I don't hit 600,000 subscribers soon. So if you want to be one of the final 5,000, I'd really appreciate your support. Okay, now this is where things get heavy. Because I'm gonna make a whole spinning background behind the train, and to do that, I'm gonna use these big gray panels, which I will add different details to. And I first decided to make a tunnel. So using masonry bricks and some arches, I think I can sell the effect of the train going through a tunnel. But the problem with connecting them is the sag. So I originally tried adding little guide wheels at the bottom, but this still allows the tread at the top to fall outwards. So I decided that a line of smooth tiles below the treads to keep them in the gap between the yellow frames would work better. And with just a few of the tunnel segments connected, it worked just fine. But with all of them, the tread still wanted to sag out. So I decided a rail at the top would work better to hold everything in. And it did. So now I can finally design all the rest of the background panels. I decided to start with a distant mountain range. So I used two different colored layers of slopes to create the stacked effect. But honestly, building stuff like this requires me to get in the zone. So I turned the camera off and just got building. Okay, the mountain range is done, so I can connect them. I even added this little train on a bridge in the distance. Then I can move them along, and I transitioned into a forest using upside down fern pieces to make the pine trees. Thank goodness I have so many translucent blue tiles because I used thousands on the background of the panels. Then I decided we needed some water. So I made an ocean with the sun setting just above the horizon, casting reflections across the water. But as I was testing it out, I realized that stuff was catching. Okay, just like this guide rail here that keeps these in line, I added one on the back all the way across just so everything stays in place. But before I add the desert along here and close everything off, I want to test it just to make sure there's no other problems or things that catch, because once I put it all together, it's gonna be really hard to fix. And it was still catching, so I spent a ton of time pivoting from these original guide assemblies to just using these plates with the tile on top. And finally, I finished off the background with a desert full of cacti. Great, so now that that's done, really all I have to do is turn it all on, right? Wrong. Very wrong. I tried to run the background, and the universal joint basically exploded on me. Well, I was testing it more, and once again, the universal joint just snapped completely. So instead of connecting the two top motors here, instead, I'm gonna move these inwards so I don't have to use any universal joints. And then I'll use these battery boxes to connect this motor and this motor and then another one on this side, rather than just using a motor here, this motor for these two, and then another motor down there. So it should work better, and I won't have to use any universal joints or weird angles, which hopefully make it way stronger and actually work. But still, as I would try and run it, it would catch on things as it went around the corners. I don't think it's gonna work like this. Realistically, I should have gotten two of these just for the background alone. One at the top, one at the bottom, so there's no wiggling. No problem with that. But I don't have the pieces to do that. So I think for now, it's just gonna have to serve as a nice stationary background while the infinite train rolls by. Is what I would say if I was gonna give up that easily. Honestly, there's been so many problems that I'm so sick of it. So first things first, I'm gonna clean off my desk because I can't build if I don't have a clean space. Now, because of the way I built the tunnel sections, the top part with the blocker keeping it on the rail is about a fourth of a plate different than all of the other ones. And it sticks out just far enough that I think that might cause a problem. So first, I tried to fix that. And honestly, without rebuilding the entire system, that's about all that I could come up with. I tried a couple different ways to guide the panels into place, but there's so much weight and so much just pulling on everything all at once that it's really hard to make stuff do what I want it to. Okay, I changed the battery, made a couple changes. Now it just better work or I have no idea what to do. Okay, and before I test to see if everything works all at the same time, remember how I said this was up to you guys if it worked or not? Well, in a video, I can search by comment. So at the end of this video, once you see how successful or unsuccessful it is, comment down below yes or no. And if we get 1000 no's, I'll try it again. But without any more holdup, let's see if it works. Yeah, well, the concept is definitely there, but it just keeps going wrong. But regardless of that, I still think the endless loop of tracks is really cool. So if you think so too, don't forget to subscribe. Thanks for watching. Bye.
